Prions are causing fatal and infectious diseases of the nervous system, such as the mad cow disease (BSE), scrapie in sheep or Creutzfeldt-Jakob disease in humans. Scientists of Helmholtz Zentrum Münc...
Life Sciences |With thousands of stinging cells that can emit deadly venom from tentacles that can reach ten feet in length, the 50 or so species of box jellyfish have long been of interest to scientists and to the ...
Life Sciences |With the advent of magnetic resonance imaging, or MRI, we have begun to appreciate how the brain continues to develop structurally through adolescence and on into adulthood. High emotionality is a cha...
Studies and Analyses |The research is a significant advance in understanding the development of the nervous system, which is essential to addressing conditions such as Parkinson's disease, Alzheimer's disease and...
Life Sciences |Research recently funded by the American Recovery and Reinvestment Act of 2009 aims to develop computational tools that will utilize next-generation petascale computers to understand genomic evolution...
Life Sciences |Since 1985, surface water temperatures measured by lake buoys have climbed 1.2 degrees per decade, about 15 percent faster than the air above the lake and twice as fast as warming over nearby land....
Earth Sciences |In the largest, most comprehensive genetic analysis of childhood-onset inflammatory bowel disease (IBD), an international research team has identified five new gene regions, including one involved in ...
Studies and Analyses |Microbes are well-known for their ability to grow in demanding and nutritionally poor environments, which has allowed them to colonise some of the most remote places on the planet. Bacteria living in ...
Life Sciences |Although recent advances have raised hopes that a protective vaccine can be developed, acquired immunodeficiency syndrome (AIDS) remains a major public health problem. Much has been learned about HIV-...
Life Sciences |The relationship between circadian and metabolic systems the researchers describe could have important implications for understanding the higher incidence of cardiovascular disease, obesity and diabet...
Life Sciences |Yousin Suh, Ph.D.Telomeres play crucial roles in aging, cancer and other biological processes. Their importance was recognized last month, when three scientists were awarded the 2009 Nobel Prize in Ph...
Life Sciences |In the study, which will be published in the January 2010 issue of the American Journal of Public Health, researchers from the division of geriatrics at the David Geffen School of Medicine at UCLA fou...
Studies and Analyses |A recent study in the Gulf of California, for example, confirmed the validity of a key concept behind marine reserves--the idea that offspring produced in a protected area can replenish the stocks of ...
Life Sciences |The information collected from genome sequencing will provide the raw data for the field of bioinformatics, where computer science and biology meet. Since the publication of the first full genome sequ...
Life Sciences |"This is a way that nitrogen is lost from an ecosystem that people have never accounted for before," said Jed Sparks, associate professor of ecology and evolutionary biology and co-author of...
